摘要： Virtual storage arrays consolidate data storage at a data center for physical and virtual computer systems at one or more branch network locations. Standalone and virtualized computer systems at a branch network location load, execute, and store their operating systems, applications, and data using virtual storage arrays and do not require any built-in or external non-volatile data storage devices such as hard disk drives or solid-state drives at the branch network location. The virtual disks of the virtual storage array are mapped to physical data storage at the data center and accessed via a WAN using storage block-based protocols. A storage block cache at the branch network location includes storage blocks prefetched based on knowledge about the computer systems at the branch network location and the behavior of their operating systems and applications.

摘要： In a network supporting transactions between clients and servers over a network path having operating characteristics to overcome, data is transported to overcome the operating characteristics using user affinities and dynamic user location information to selectively preload data, or representations, signatures, segments, etc. of data, in order to overcome the one or more operating characteristic. Examples of operating characteristics to overcome include bandwidth limitations, errors and latency. The dynamic location information can be stored in data structures accessible by agents of a data server and the data structures are populated based on user activities with respect to proxies associated with user locations, or the dynamic location information can be obtained implicitly as proxies maintain connections after termination by clients and the use of those maintained connections for preloading of data for the users associated with those clients. The data being preloaded can be protocol-specific data or protocol-independent data.

摘要： Virtual storage arrays consolidate branch data storage at data centers connected via wide area networks. Virtual storage arrays appear to storage clients as local data storage; however, virtual storage arrays actually store data at the data center. The virtual storage arrays overcomes bandwidth and latency limitations of the wide area network by predicting and prefetching storage blocks, which are then cached at the branch location. Virtual storage arrays leverage an understanding of the semantics and structure of high-level data structures associated with storage blocks to predict which storage blocks are likely to be requested by a storage client in the near future. Virtual storage arrays determine the association between requested storage blocks and corresponding high-level data structure entities to predict additional high-level data structure entities that are likely to be accessed. From this, the virtual storage array identifies the additional storage blocks for prefetching.

摘要： In a network that conveys requests from clients to servers and responses from servers to clients, a network transaction accelerator for accelerating transactions involving data transfer between at least one client and at least one server over a network comprising a client-side engine, a server-side engine and a transaction predictor configured to predict, based on past transactions, which transactions are likely to occur in the future between the client and server. The transaction predictor might be in the server-side engine, the client-side engine, or both. The client-side engine receives indications of requests from the client, a transaction buffer for storing results of predicted transactions received from the server or the server-side engine ahead of receipt of a corresponding request, and a collator for collating the requests from the client with the stored results or received results, wherein a request and a response that are matched by the collator are identified and the matched response is provided to the client in response to the matched request. The server-side engine receives indications of transactions including requests and responses and conveys requests to the server in response to actual transactions or predicted transactions.

摘要： A system of network proxies distributes data to multiple servers. Each network proxy is associated with a server. A network proxy intercepts a client request for data. If the network proxy determines that the request can be served using a copy of data stored on the local server, rather than the data stored on a remote server, it diverts the request to the local server. If the network proxy determines that the request cannot be served using a data from the local server, the network proxy diverts the request to a remote server storing the primary copy of the data. A server map specifies the locations of the primary copies of data. When a primary copy of data is updated on one of the servers, the associated network proxy propagates the updated data to the other servers. The servers can provide data from files, e-mail services, databases, or multimedia services.

摘要： Self-discovering transaction accelerators improve communications between a client and a server. A client directs a message to a server. A client-side transaction accelerator intercepts the message, terminates the connection with the client, and accelerates the request by replacing segments of data with references. The accelerated request is forwarded to a server-side transaction accelerator through a new connection. The server-side transaction accelerator reconstructs the message by replacing the reference with segment data in a persistent segment store accessible to the server-side transaction accelerator. The reconstructed request is then provided to the server. Accelerations may occur in any direction of communication. Persistent segment stores can be pre-populated with segment data from other transaction accelerators and anticipated transactions. The persistent segment store can store segments that are data segmented based on content of the data and can be independent of transaction protocol, application, and device.
摘要翻译：自发发现事务加速器可改善客户端与服务器之间的通信。客户端将消息指向服务器。客户端事务加速器拦截消息，终止与客户端的连接，并通过用引用替换数据段来加速请求。加速请求通过新连接转发到服务器端事务加速器。服务器端事务加速器通过将服务器端事务加速器可访问的持久段存储中的段数据替换为引用数据来重构消息。然后将重建的请求提供给服务器。加速可能发生在任何通信方向。可以使用来自其他事务加速器和预期事务的段数据预先填充持久性段存储。持久段存储可以存储基于数据内容进行数据分段的段，并且可以独立于事务协议，应用和设备。
